My friend was a theatre manager in the 90's and I got to see all my movies for free. That made it easier to walk out of.
Sadly, If I had paid, I would have stayed. Then again, if I had to pay I wouldn't have gone in as you said
The other was Mr. Wrong and I went to that one drunk with friends and walked out early to go and chat with my theatre friend instead of watching the rest of this crap.
